Answer:
Villus, plural villi, in anatomy any of the small, slender, vascular projections that increase the surface area of a membrane. ... The villi of the small intestine project into the intestinal cavity, greatly increasing the surface area for food absorption and adding digestive secretions.
<span>Sam, a mendalien with black eyes and green skin, has a parent with orange eyes and white skin. Sam has a dominant phenotype expressed but he has a parent with a recessive phenotype which means he has a heterozygote gene.
Carole is a mendalien with orange eyes and white skin. Since Carole express both recessive phenotypes she should be homozygote recessive.
The key to this problem is how Sam dominant gene will be inherited. Since there are two heterozygote genes, it will be 50% dominant gene inherited for each phenotype. Then the result should be:
25% Dominant + Dominant =</span>black eyes and green skin<span>
25% Dominant + Recessive =</span>black eyes and white skin
25% Recessive + Dominant =orange eyes and green skin
25% Recessive + Recessive =orange eyes and white skin
<span>Glycolysis.
Hope this helps (:

Answer:
An experiment where an antibiotic is tested against bacteria. The antibiotic can vary in its concentration for example, different amounts are applied to a sample of bacteria to see if it is affected by the action of the antibiotic and if so, in what concentration. So, the independent variable is the concentration of antibiotic while the dependent variable is the survival (or not) of the bacteria.
Explanation:
An independent variable is a variable that represents a quantity that the scientist modifies in an experiment. A dependent variable represents a quantity whose value depends on how the independent variable is modified. This is the variable being studied and measured.
So, an example of this applied to bacteria or viruses could be:
<u>An experiment where an antibiotic is tested against bacteria</u>. The antibiotic can vary in its concentration, different amounts are applied to a sample of bacteria to see if it is affected by the action of the antibiotic and if so, in what concentration. So, the independent variable is the concentration of antibiotic while the dependent variable is the survival (or not) of the bacteria.
To complete the experiment, an antibiotic whose effect is already known can be used as a positive control. That is, it is already known to kill the bacteria. And as a negative control you can simply use water, which has no effect and is known not to kill the bacteria. In this way, we validate the results and make sure that there is not something else that is affecting the bacteria and that only the antibiotic being studied has an influence.
